I think this is relevant to all of us as a whole, to compare and contrast the hands we're dealt. It's certainly worrying that EK are taking this line.
It flies in the face of an open safety culture where individuals feel comfortable to admit mistakes so that an airline can monitor trends and train them out. Blaming pilots rather than looking at all the factors involved is merely laying the foundations for the next accident.
This email will serve to increase stress levels, push mistakes to be covered up and make for a worse place to work. It's arse covering of the higher order, managers threatening pilots so they can report to those above that they've 'dealt' with the issue. It's merely compounded an existing issue.
I feel for the guys involved as no one makes mistakes on purpose or sets out to have a bad day. Being PM and monitoring effectively is hard enough when fully alert, but when flying through the night becomes that much harder. Add to this now the complete b******s in the email above, the stressors are heightened.
